The 28-year-old was the subject of a surge of bets from punters overnight, with the Eagles moving into pole position to land the shot-stopper ahead of Brighton and Hove Albion, Newcastle United and Watford.

Huddersfield Town, Southampton and Swansea City are also in the market offered by Leo Vegas.

Tom Jacobs of LeoVegas Sport said: "Wayne Hennessey has admitted he's not a big fan favourite at the moment, and according to our punters, Palace fans might have one soon with Robin Olsen linked to the club.

"He was a massive 10/1 overnight to join Hodgson's squad, but at evens – it's looking likely he'll make the trip from Copenhagen to Croydon."
